json字符串反序列化成类的集合

Question

用JSON序列化和反序列化的类就行了，再说，JSON用单引号较好。

Answer 1

public static List<T> JSONStringToList<T>(string JsonStr)
        {
            JavaScriptSerializer Serializer = new JavaScriptSerializer();            List<T> objs = Serializer.Deserialize<List<T>>(JsonStr);            return objs;
        }
我用了这个反序列化的方法，但是报错：
输入的对象无效。应该是“：”或“｝”

Answer 2

json格式不是双引号才正规么？
单引号我也想啊，但是我只是接收json而已，格式是那边定的

Answer 3

把string JsonStr = @" 和最后一个 " 去掉试试。

Answer 4

        /// <summary>
        /// JSON反序列化
        /// </summary>
        public static T JsonDeserialize<T>(string jsonString)
        {            //将"yyyy-MM-dd HH:mm:ss"格式的字符串转为"\/Date(1294499956278+0800)\/"格式            string p = @"\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2}";            MatchEvaluator matchEvaluator = new MatchEvaluator(ConvertDateStringToJsonDate);            Regex reg = new Regex(p);            jsonString = reg.Replace(jsonString, matchEvaluator);            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));            using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)))
            {
                T obj = (T)ser.ReadObject(ms);
                return obj;
            }
        }
        /// <summary>
        /// 将时间字符串转为Json时间
        /// </summary>
        private static string ConvertDateStringToJsonDate(Match m)
        {            string result = string.Empty;            DateTime dt = DateTime.Parse(m.Groups[0].Value);            dt = dt.ToUniversalTime();            TimeSpan ts = dt - DateTime.Parse("1970-01-01");            result = string.Format("\\/Date({0}+0800)\\/", ts.TotalMilliseconds);            return result;        }调用   JsonDeserialize<model>(json字符串);

Answer 5

using System.Web.Script.Serialization;
using System.Runtime.Serialization.Json;
 
public static T JsonDeserialize<T>(string jsonString)
    {
        DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
        using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)))
        {
            return (T)ser.ReadObject(ms);
        }
    }
 
 
     
    List<model> list = JsonDeserialize<List<model>>(str);

Answer 6

如果JSON中出现时间类型 。你这个解析通过不了的！

Answer 7

正确的"[{""PlanId"":""201212170001"",""Type"":""Cable"",""PlanContentId"":""9"",""InspectGroupId"":""3"",""InspectContentId"":""1"",""InspectContentValue"":""XXX"",""Longitude"":""120.2113312"",""Latitude"":""30.123123"",""InspectDate"":""20121217100330"",""UserId"":""1""},
{""PlanId"":""201212170001"",""Type"":""Cable"",""PlanContentId"":""9"",""InspectGroupId"":""3"",""InspectContentId"":""1"",""InspectContentValue"":""XXX"",""Longitude"":""120.2113312"",""Latitude"":""30.123123"",""InspectDate"":""20121217100330"",""UserId"":""1""},
{""PlanId"":""201212170001"",""Type"":""Cable"",""PlanContentId"":""9"",""InspectGroupId"":""3"",""InspectContentId"":""1"",""InspectContentValue"":""XXX"",""Longitude"":""120.2113312"",""Latitude"":""30.123123"",""InspectDate"":""20121217100330"",""UserId"":""1""}]"
你的错误的
"[{""PlanId"":""201212170001"",""Type"":""Cable"",""PlanContentId"":""9"",""InspectGroupId"":""3"" ,""InspectContentId"":""1"",""InspectContentValue"":""XXX"",""Longitude"":""120.2113312"",""Latitude"":""30.123123""，""InspectDate"":""20121217100330"",""UserId"":""1""},{""PlanId"":""201212170001"",""Type"":""Cable"",""PlanContentId"":""9"",""InspectGroupId"":""3"" ,""InspectContentId"":""1"",""InspectContentValue"":""XXX"",""Longitude"":""120.2113312"",""Latitude"":""30.123123""，""InspectDate"":""20121217100330"",""UserId"":""1""},{""PlanId"":""201212170001"",""Type"":""Cable"",""PlanContentId"":""9"",""InspectGroupId"":""3"" ,""InspectContentId"":""1"",""InspectContentValue"":""XXX"",""Longitude"":""120.2113312"",""Latitude"":""30.123123""，""InspectDate"":""20121217100330"",""UserId"":""1""}]";
把这两部分贴到能显示半角全角的编辑器中看看区别。空格和全角都有

Answer 8

 var ary = Regex.Matches(JsonStr, @"{""PlanId"":""(?<PlanId>[^""']+)"",""Type"":""(?<Type>[^""']+)"",""PlanContentId"":""(?<PlanContentId>[^""']+)"",""InspectGroupId"":""(?<InspectGroupId>[^""']+)"" ,""InspectContentId"":""(?<InspectContentId>[^""']+)"",""InspectContentValue"":""(?<InspectContentValue>[^""']+)"",""Longitude"":""(?<Longitude>[^""']+)"",""Latitude"":""(?<Latitude>[^""']+)""，""InspectDate"":""(?<InspectDate>[^""']+)"",""UserId"":""(?<UserId>[^""']+)""}").OfType<Match>().Select(t => new
            {
                 PlanId = t.Groups["PlanId"].Value,
                Type = t.Groups["Type"].Value,
                PlanContentId = t.Groups["PlanContentId"].Value,
                InspectGroupId = t.Groups["InspectGroupId"].Value,
                InspectContentId = t.Groups["InspectContentId"].Value,
                InspectContentValue = t.Groups["InspectContentValue"].Value,
                Longitude = t.Groups["Longitude"].Value,
                Latitude = t.Groups["Latitude"].Value,
                InspectDate = t.Groups["InspectDate"].Value,
                UserId = t.Groups["UserId"].Value
            }).ToArray();

Answer 9

var ary = Regex.Matches(JsonStr, @"(?<={)[^}]+(?=})").OfType<Match>().Select(t =>
                {
                    Dictionary<string, string> dict = new Dictionary<string, string>();
                    foreach (var m in Regex.Matches(t.Value, @"[""']([^""']+)[""']:[""']([^""']+)[""'](?=,|})").OfType<Match>().Select(tt =>
                                  new
                              {
                                  key = tt.Groups[1].Value,
                                  value = tt.Groups[2].Value
                              }))
                        dict.Add(m.key, m.value);
                    return dict;
                }).ToArray();

Answer 10

你用错类了，是 DataContractJsonSerializer类。

Answer 11

提问#9楼private static string ConvertDateStringToJsonDate(Match m) 
参数有什么作用？
